No Room for Doubt

I am a person who loves to compete but I only compete with myself. I use comparison as a way of measuring myself. If who I compare to exceeds me then I know that I have something to work on and I use it as my motivation to strive. I know that I live to continuously grow myself so I think of other people as examples of what I want or don't want to be. I know that I'm working to be a better version of myself so I have no reason to compete against what I cannot fully understand. Concentrating on what I do understand (myself), I have no room for doubt because everything I do will achieve growth. I am the only person I can make the most of, understand everything about and know what heights to push for. I know that competing only with myself contributes to my progress.
